trib.al – FERGUSON Mo. (Reuters) – Missouri’s governor declared a state of emergency on Monday and authorized the state’s National Guard to support police in case of violence after a grand jury decides whether to indict a white police officer who fatally shot an unarmed black teenager. “As part of our ongoing efforts to plan and be prepared for any contingency, it is necessary to have these resources in place in advance of any announcement of the grand jury’s decision,” Governor Jay Nixon said in a statement.
